Graphite gland packing - GR8800 Special

Graphite packing - GR8800

Features

The graphite gland compression packing GR8800 is made with continuous PAN graphite yarns, pure graphite powder and Inorganic inhibitor of corrosion

Composition

Special braided packing made by PAN continuous yarns, The impregnation occurs in three phases: at first on the single yarns, second during the braiding and at end on the body. The impregnation compound includes pure colloidal graphite and the inhibitor of corrosion to minimize the stem corrosion's risks. GR8800 offer a great recovery along the time because the PAN yarns do not show aging.

Applications

GR8800 is an excellent graphite packing suitable for valve in Steam, Hydrocarbon and Petrochemical services, for Feed Boiler pumps and Soot Blowers. Avoid the strong oxidizers media, hot combustion gases and hot air over 450°C. Available also in the style GR8800/R with continuous Inconel® wire PAN yarns.
